It is interesting to note that the assimilation backlog (which has bee averaging 400k lately) started when the replica was brought back online. The Assimilation/Replica graphs look very similar over time. |

It is good to see the system back. Thanks to the people who work so hard to keep this system going. It is going to be a rough recovery after such a long down time. |

126 is the Scheduler and that is probably just an indication of a lot of traffic hitting it. |

I've managed to send back all my completed tasks (from the two biggest systems). but getting project has no tasks available. so it seems they haven't opened the door yet. Set NNT, and you'll be able to report old tasks and will get you past the "HTTP internal error". you do not need to wait the 5min timer for reporting tasks. just click "Update" over and over until all of your old tasks are sent back. I set max_tasks_reported to 250. even thousands of tasks only takes a few mins to report them all. then wait patiently for more work lol. Seti@Home classic workunits: 29,492 CPU time: 134,419 hours |

I see the problems are continuing....Actually this problem goes back Years, it's just for the first couple of Years there were few people reporting about the problem. Logs were posted, for years, showing how the Scheduler was simply ignoring work requests and just sending a few random tasks ever so often. It first started with the introduction of the BLC tasks in 2016. Finally enough people were reporting the problem that a serious attempt was made to solve the problem. It was found that as long as there was just One type of task in the cache there wasn't a problem, the problem started as soon as a different type task was added to the cache. At this point the cache was mainly filled with BLC tasks, and only a couple Arecibo files would be added per a week. It was found the problem was solved by sending Arecibo VLARs to the GPUs and this seemed to work, as long as there are only a Few Arecibo Files split a week. Recently Many More Arecibo Files have been added to the cache than just a couple a week, in fact, there is a constant supply. Now, the Exact Same Problem has returned, the exact same problem which has been present for Years. It would seem the process that chooses which task to send hangs at some point and No task is chosen to be sent. As long as there is just One type of task in the cache, the problem doesn't appear. This is how BETA Works BTW. Only One type of task is in the cache at one time, for the past few weeks BETA has only been sending Arecibo tasks. When that file is finished at BETA, probably, a BLC File will be loaded, again, One type of File present in the cache at one time. I'm willing to bet that if there were only One type of File in the SETI Main cache the recent Scheduler problems would disappear, just as has been the case for Years. Hopefully those 'Lost' Arecibo files will be finished SOON and we will go back to having only a couple of Arecibo Files a week. Or, someone could manually Stop the Arecibo Files long enough to determine if that is indeed the problem. |

much needed db purging is happening ... from 9 million down to 7 million and hopefully lower. I think splitting, and giving out WUs will get better once the db purging is not the main focus. |

I wouldn't blame the scheduler exactly for having problem with multiple WU types. More that its decision time for allocating tasks increases under high server loads causes timeouts - http or data reads. Also it seems to have a load watchdog, where as now, it likes to only give 1 task at a time per computer thread for downloads. Likely due to too many dropped calls to it. |

I am currently getting pretty much gpu tasks with very few or no cpu tasks. Pretty much normal. Indulging in our favorite guessing game, I'm guessing that if you request both GPU and CPU work, it will class the work as GPU unless it can give you enough to fill the GPU cache and get a start on CPU's needs. At least, that seems to be what I consistently see here. Would only make sense. |
